IMPROVEMENT IN SEED-DRILLS.

Specification forming part of Letters Patent No. 30,768, dated November 27, 1860.

To all 'whom t may concern:

Be it known that I, A RNTON SMlTH, of Girard, in the county of Macoupin and State of Illinois, have invented a new and useful Improvement in Seed-Drills; and 1 do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making part ofl this specification.

With reference to the accompanying drawings, Figure 1 is a plan of my improved drill. Fig. 2 is a sectional view from the rear. Fig. 3 is a side view. Fig. 4 is a representation of details.

A A are the wheels, one of which is fast, and the other free to turn upon the axle B.

C is the frame, and rests in bearings upon axle B. On the axle B are fastened the rolls D, each of which is furnished with three rows of cells ranged around its periphery.

Directly over the axle is arranged the seedhox E, in the bottom of which box is arranged openings G, directly over the rolls D. A slide, F, which is furnished with perforations corresponding to theopenings in the bottom ofthe seed-box, is iittcd under the box, so as to slide and' cover a greater or less portion of the openings Gr and one or more or fractional parts of the rows of cells in the rolls l). A rod, H, passes down by the side of the seedboX, and, by means oi' an arm at its lower end connected to the slide and a crank or. handle at its top end, serves to adjust the slide F. The cells in the rolls` D receive the seed from the apertures formed by the openings G and the perforated slide F, and, as they revolve with the axle B, drop it through the hose I into the seed-tubes J, whence it falls into the furrow made by the plows K. The plows K are connected to the draw-beams L, which are forked at their forward end to give them stability, and arc there jointed to the frame. A bar, M, is arranged across the frame, so as to move up and down freely in the guides N, which are last to the frame.

To the bar M are made fast the springs O. The lower end of these springs embrace the beams L and keep them pressed downward with an elastic force, so that when the rolling cutters P, which are rigidly secured by their carriers Q to the seed-tubes and plows J K, chance to come in contact with a stone or other obstruction too hard to be cut by them, the seed-tubes and plows may be free to rise lthe ends of the bolt-rods.

and be carried safely by the rolling of the out ter over and past such obstruction. A windlass or elevator, R, is arranged at the rear end of the frame, and is furnished with the lever S, by which to operate it. Each of the seedtubes is connected to this elevator by means of a strap, T.

When it is required to lift the plows from the ground, or to vary the depth of their operation, it is done hy turning up the lever S.

Upon the bar M are arranged the sliding bolt-rods U and lever V, by means of which the bar M maybe adjusted at any required elevation in the guides N, these guides N being furnished with a series of holes to receive By these means the plows may be made to work to any suitable depth, or be elevated above ground en,- tirely.

W is a tongue or pole by which to attach the team.

X is a latch to hold up the lever S.

The several parts may be made of any snitable materials usually employed for like purposes.

Having described the construction, the operation is as follows: The seed-box being supplied with seed and the team attached, the drill is made to move forward, and the wheel, which is made fast upon the axle, thereby gives motion to rolls D, and they, receiving the seed as described, drop it through the hose and seed-tubes just in rear of the plows which form the furrow, the earth which falls back into the furrow covering it. The rolling cutters cut the smaller obstructions in advance of the plows and carry them safely over such as they do not cut. i

Having described the construction and operation ot' my improvement, what I claim as new, and desire to secure by Letters Patent, is as follows:

In combination with seed-tubes J J J and plows K K K, the arrangement of the rolling cutters I) I I and springs O O 0, when used in' connection with the sliding bar M, bolt-rods U, and elevator R, in the manner substantially as and for the purpose set forth.

In testimony of which invention I have here- 4unto set my hand.

ARNTON SMITH.
